The Strength of materials may broadly be defined as that branch of Engineering-Science, which deals with the relations between externally applied loads and their internal effects on bodies.
The bodies are no longer assumed to be rigid and deformations are of major interest. During deformation the external forces acting upon the body do work. This work is transferred completely or partially into potential energy of strain. If the forces which produce the deformation of the body are gradually removed, the body returns or try to return to its original shape. During this return the stored potential energy can be recovered in form of external works. The main concern of the subject is regarding three S's namely strength, stiffness and stability of various load carrying members.
